After doing searching in forum, all user have missing lda services. Then, we applied this script: updateLDAPValues_080_to_081.py. Now, all users have lda service enabled. The maillog shows normal and delivery to existing user mailbox succesfully.

But, when we create new user, the new user still has missing lda service. Do you have any suggestion how to make all new user creation has lda service enabled automatically?
